i SPECIFICATION. forming part of Letters Patent No. 554,308, datedFebruary 11, 1896.

Application filedNovember 22, 1894. Serial No. 529,613` (No model.)

To all ich/m it maty concerne it4 known that DANIEL M. REDMOND, de-

` ceased, late a citizen of the'United States, and

a resident of the city of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, did in his lifetime invent certain new anduseful Improvements in Oil-Holders, of which the following` is aspecification, furnished by nie, DANIEL H. REDMOND, a citizen of theUnited States, residing at Philadelphia, Pennsylvania, administrator ofthe estate of said DANIEL M. REDMOND, deceased.

One object of the present invention is to z provide an eflicient,reliable and comparatively inexpensive holder for kerosene-oil, benzine,and other inflammable fiuids, which is at all times filled, whereby theformation and collection of explosive gases are obviated, and in whichthere is no internal pressure, whereby danger of leakage is avoided 3and to this end the invention consists of the improvements hereinafterdescribed and claimed.

The nature, characteristic features, and scope of the invention will bemore fully understood from the following desc1'iption,taken inconnection With the accompanying' drawing, forming part hereof, and inwhich is illustrated partly in elevation and partly in central sectionan oil-holder embodying' features of the invention. i

In the drawing, 1. is a tank or vessel of any preferred size and shape,and in the example illustrated this vessel is located beneath thesurface A B of the `ground, and is provided with an oil-inlet 2 and anoil-offtake 3, both of which extend above the level of the ground, thelatter not so far as the former. The oilinlet 2 is or maybe provided atits upper end with a stopper or stop-cock 4. The offtake 3 is providedwith a stop-cool; 5.

6 is a pipe or vessel that communicates with the interior of the tank orvessel 1, near the bottom thereof, and that is open at its upper end forthe reception ,of a supply of fiuid, as water, heavier than oil, issuingfrom the supply-pipe 7 and Controlled by the stop-Cook 8, and for theoverfiow of such fluid.

9 is a cup adapted to receive the overfiow from the top of the pipe orvessel 6, and to lead the same away through the waste-pipe 10.

11 is a petcock or spigot located below the opening and closing thepetcock or spigot 11.

The mode of operation of the above-described apparatus is as follows:The tank or vessel 1 is filled with oil, benzine or other inv flammablematerial, for example, level with thepetcock 11. For this purpose thepetcock 11 may be opened and the oil, benzine or other infiammablematerial poured into the in'let 2 until it appears at the petcock.During this operation the supply-pipe 7 is closed by means of the valve8. The pe'tcock 11 is then closed and water is permitted to escape fromthe supply-pipe 7 and to collect4 in the vessel or pipe 6. The weight ofthe waterlin the vessel 6 displaces the lighter oil, benzine or otherinflammable material and causes it to rise in and fill the vessel ortank 1, until finally a state of equilibrium between the two liquids isestablished. For example,

- the oil rises to the level indicated by the line a b, and the Waterrises to the level indicated by'the line c cl. Under these circumstancesthe weight of the columns of oill and water balance each other, so thatadditional water leaving the supply-pipe 7 overfiows from the pipe 6into the cup 9, and thus escapes from the waste-pipe 10. However, whenthe cock 5 is opened oil fiows from it by reason of the fact that thelevel of the oil a b is above it, and the space which was occupied bythe oil so drawn oif is immediately filled with water that iiows inthrough the pipe or vessel 6.

From the foregoing description it will be obvious that the vessel 1 isalways full, so' that there are no spaces in which eXplosiVe gases,vapors and the like can collect, and that since the. oil simply remainssupernatant or fioating upon the water the apparatus is not subj ectedto internal pressure, whereby leakage and its consequent dangers areavoided. Vhen all the oil has been drawn off the vessel 1 is, of course,filled with water. However, this water is expelled during' the refillingoperation above described by reason of the fact that the petcock 11 isopen, thus re- IOO dueing the heig'ht of the Water column, and the inlet2 is filled to its top With oil, thus inoreasing the height of the oilcolumn. By inoreasing the height of the top of the pipe (i the Weight ofthe column of heavier fluid, as Water, is inoreased, so that the level ab of the lighter fluid, as oil, may be raised, thus permitting thestop-Cook 5 and offtake 3 to be placed farther above the ground-line AB. The absence of internal pressure in the vessel 1 permits of the useof a fioat 14 and indeX-rod 15, that is attaohed to the float and Worksin a tube 1G, projeoting` upward from the vessel 1, as shown. This float14 is so weighted or loaded as that it floats on Water and sinks in oil,and thus rises and falls as the line c d rises and falls, andeonsequently eauses the indeX-rod 15 to indioate the quantity of oilcontained in the vessel 1. 17 is a oap that may be used for covering`the upper end of the tube 1(3, as required.

It will be ovious to those skilled in the art to .which the inventionrelates that modifications may be made in details without departing fromthe spirit thereof. Ilence it should not be limited to the preciseconstruction. and arrangement of parts hereinabove set forth andillustrated in the aceompanying drawings; but,

Having thus deseribed the nature and objeets of the invention of thesaid DANIEL M. REDMOND, deceased,=what I, his administrator, olaim asnew, and desire to secure by Letters Patent, is-

The combination in an oil-holder, With an oil-vessel closed at its top,an immovable pipe open at its upper end and communicating' With thelower portion of said vessel at its other end and provided intermediateof its ends With a petcook, and means for introduoing' Water into theopen end of said pipe, of a cup provided with a waste-pipe andeontaining said petcook and underlying` the open end of the fixed pipe,an oil-offtake, and an oil-inlet, substantially as desoribed.

In testimony whereof l have hereunto signed my name.

DANIEL H. REDMOND, Administrator ofihe Eszfm'e of Dan z'eZ III. Redmoml.
